8.3.1. General information about PostgreSQL

PostgreSQL — open source relational database management system (RDBMS) that emphasizes extensibility and SQL compliance. PostgreSQL supports transactions with atomicity, consistency, isolation, and durability (ACID) properties, automatically updated views, materialized views, triggers, foreign keys, and stored procedures. Due to its flexibility, speed and reliability, it is used by many modern web apps.

Available PostgreSQL versions:

  • 16.11
  • 17.7
  • 18.1

The major version (numbers before the dot) is selected only at the time of order. The major version can only be changed by ordering a new instance.

The minor version (numbers after the dot) increases for the instance as official PostgreSQL updates are released.

Available plans differ:

  • Number of available processor cores.
  • Amount of RAM.
  • Capacity of disk space.

While using PostgreSQL the plan can be changed.
